SAFETY121
The air bag system must be ready to protect you
in a collision. The Occupant Restraint Controller
(ORC) monitors the internal circuits and
interconnecting wiring associated with the
electrical Air Bag System Components. Your
vehicle may be equipped with the following Air
Bag System Components:
Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
NOTE:
Vehicles with front passenger seat deleted will
not be equipped with the Seat Belt Buckle
Switch, Seat Belt Pretensioner, Supplemental
Seat Mounted Side Airbag, and Seat Track Posi -
tion Sensors for the front passenger. If the front passenger and/or rear seats have
been removed do not ride in those areas.
All passenger occupants within the vehicle must
be in a seat equipped with a Seat Belt System
and Head Restraint for the safety of the
passenger.
Air Bag Warning Light
The Occupant Restraint Controller
(ORC) monitors the readiness of the
electronic parts of the air bag system
whenever the ignition switch is in the
START or ON/RUN position. If the ignition switch
is in the OFF position or in the ACC position, the
air bag system is not on and the air bags will not
inflate.
The ORC contains a backup power supply
system that may deploy the air bag system even
if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in
the instrument panel for approximately four to
eight seconds for a self-check when the ignition
switch is first in the ON/RUN position. After the
self-check, the Air Bag Warning Light will turn
off. If the ORC detects a malfunction in any part
of the system, it turns on the Air Bag Warning Light, either momentarily or continuously. A
single chime will sound to alert you if the light
comes on again after initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could
affect the air bag system. The diagnostics also
record the nature of the malfunction. While the
air bag system is designed to be maintenance
free, if any of the following occurs, have an
authorized dealer service the air bag system
immediately.
The Air Bag Warning Light does not come on
during the four to eight seconds when the
ignition switch is first in the ON/RUN position.
The Air Bag Warning Light remains on after
the four to eight-second interval.
The Air Bag Warning Light comes on intermit
-
tently or remains on while driving.
NOTE:
If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant
Restraint Controller (ORC) may also be
disabled. In this condition the air bags may not
be ready to inflate for your protection. Have an
authorized dealer service the air bag system
immediately.

176STARTING AND OPERATING
NOTE:
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning is active Normal (Fixed Speed)
Cruise Control is still available. For additional
information refer to “Normal (Fixed Speed)
Cruise Control Mode” in this section.
If weather conditions are not a factor, the driver
should examine the sensor. It may require
cleaning or removal of an obstruction. The
sensor is located in the center of the vehicle
behind the lower grille.
To keep the ACC System operating properly, it is
important to note the following maintenance
items:
Always keep the sensor clean. Carefully wipe
the sensor lens with a soft cloth. Be cautious
not to damage the sensor lens.
Do not remove any screws from the sensor.
Doing so could cause an ACC system
malfunction or failure and require a sensor
realignment.
If the sensor or front end of the vehicle is
damaged due to a collision, see an autho -
rized dealer for service.
Do not attach or install any accessories near
the sensor, including transparent material or
aftermarket grilles. Doing so could cause an
ACC system failure or malfunction.
When the condition that deactivated the system
is no longer present, the system will return to
the “Adaptive Cruise Control Off” state and will
resume function by simply reactivating it.
NOTE:
If the “ACC/FCW Unavailable Wipe Front
Radar Sensor” message occurs frequently
(e.g. more than once on every trip) without
any snow, rain, mud, or other obstruction,
have the radar sensor realigned at an autho -
rized dealer.
Installing a snow plow, front-end protector,
an aftermarket grille or modifying the grille is
not recommended. Doing so may block the
sensor and inhibit ACC/FCW operation.
Service ACC/FCW Warning
If the system turns off, and the instrument
cluster displays “ACC/FCW Unavailable Service
Required” or “Cruise/FCW Unavailable Service
Required”, there may be an internal system
fault or a temporary malfunction that limits ACC
functionality. Although the vehicle is still
drivable under normal conditions, ACC will be
temporarily unavailable. If this occurs, try
activating ACC again later, following an ignition
cycle. If the problem persists, see an authorized
dealer.
PRECAUTIONS WHILE DRIVING WITH
ACC
In certain driving situations, ACC may have
detection issues. In these cases, ACC may
brake late or unexpectedly. The driver needs to
stay alert and may need to intervene.
Towing A Trailer
Towing a trailer is not advised when using ACC.

20_LA_OM_EN_USC_t.book Page 176

194STARTING AND OPERATING
(Continued)
Perform the maintenance listed in the
“Scheduled Servicing”. Refer to “Scheduled
Servicing” in “Servicing And Maintenance” for
the proper maintenance intervals. When towing
a trailer, never exceed the GAWR or GCWR
ratings.
Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h) when towing while using a full size spare tire.
Proper tire inflation pressures are essential
to the safe and satisfactory operation of your
vehicle. Refer to “Tires” in “Servicing And
Maintenance” for proper tire inflation
procedures.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer. Refer to
“Tires” in “Servicing And Maintenance” for
the proper inspection procedure.
When replacing tires, refer to “Tires” in
“Servicing And Maintenance” for the proper
tire replacement procedures. Replacing tires
with a higher load carrying capacity will not
increase the vehicle's GVWR and GAWR
limits.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake
system or vacuum system of your vehicle
with that of the trailer. This could cause inad -
equate braking and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer
with electronically actuated brakes. When
towing a trailer equipped with a hydraulic
surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers
over 1,000 lbs (453 kg) and required for
trailers in excess of 2,000 lbs (907 kg).
Total weight must be distributed between
the tow vehicle and the trailer such that the
following four ratings are not exceeded :
Max loading as defined on the “Tire and
Loading Information” placard.
GTW
GAWR
Tongue weight rating for the trailer
hitch utilized.
CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is
driven. The engine, axle or other parts could
be damaged.
WARNING! (Continued)
Then, during the first 500 miles (805 km)
that a trailer is towed, do not drive over
50 mph (80 km/h) and do not make starts
at full throttle. This helps the engine and
other parts of the vehicle wear in at the
heavier loads.
CAUTION! (Continued)

20_LA_OM_EN_USC_t.book Page 194

220IN CASE OF EMERGENCY
NOTE:
For vehicles so equipped, do not attempt to
install a center cap or wheel cover on the
compact spare.
Refer to “Compact Spare Tire” and to
“Limited-Use Spare” under “Tires” in
“Servicing And Maintenance” for additional
warnings, cautions, and information about
the spare tire, its use, and operation.
8. Install the lug nuts with the cone shaped end of the lug nut toward the wheel. Lightly
tighten the lug nuts.
9. Lower the vehicle to the ground by turning the jack handle counterclockwise.
10. Refer to “Wheel And Tire Torque Specifi -
cations” in “Technical Specifications”
section for proper lug nut torque. 11. Stow the jack, tools and flat tire. Make sure
the base of the jack faces the front of the
vehicle before tightening down the fastener.
TIRE SERVICE KIT — IF EQUIPPED
Small punctures up to 1/4 inch (6 mm) in the
tire tread can be sealed with Tire Service Kit.
Foreign objects (e.g., screws or nails) should not
be removed from the tire. Tire Service Kit can be
used in outside temperatures down to
approximately -4°F (-20°C).
This kit will provide a temporary tire seal,
allowing you to drive your vehicle up to
100 miles (160 km) with a maximum speed of 50 mph (80 km/h).
TIRE SERVICE KIT STORAGE
The Tire Service Kit is located in the trunk.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
3.6L AND 5.7L ENGINES
These engines are equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is time to
take your vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for the vehicle.
Operating conditions such as frequent
short-trips, trailer tow, and extremely hot or cold
ambient temperatures will influence when the
“Change Oil” or “Oil Change Required” message
is displayed. Severe Operating Conditions can
cause the change oil message to illuminate as
early as 3,500 miles (5,600 km) since last
reset. Have your vehicle serviced as soon as
possible, within the next 500 miles (805 km).
The “Oil Change Required” message will be
displayed in the instrument cluster and a single
chime will sound, indicating that an oil change
is necessary.An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change. If a scheduled oil change
is performed by someone other than an
authorized dealer, the message can be reset by
referring to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for
fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) or
350 hours of engine run time if the vehicle is
operated in a dusty and off-road environment,
or is operated predominantly at idle or only very
low engine RPM. This type of vehicle use is
considered Severe Duty.
Once A Month Or Before A Long Trip:
